DYNO: A notation to leverage dynamic network effects in PaaS ecosystems

Platform-as-a-service offerings continuously gain importance as two-sided markets, offering Software-as-a-Service (SaaS) to the respective customers. Market success is achieved by platforms, which excel in shaping ecosystems of users and autonomous SaaS suppliers around their basic value proposition - and in controlling quality of service in function of customer requirements. In this paper, we suggest a notation for dynamic networks `DYNO´, designed to help platform providers in creating PaaS, optimized on their specific requirements. In addition, DYNO gives support in properly allocating control mechanisms to guarantee high quality of service. In a use-case we describe how business analysts and service engineers may use DYNO-models to conceive PaaS ecosystems.
